An active-active cluster is typically made up of at least two nodes, both actively running the same kind of service simultaneously. This allows the load balancer to distribute workloads across more nodes and improve throughput and response times.

A single node can be Master in a VRRP instance at a time. Hence, in order to configure an active / active cluster, you must set up two VRRP instances where each ALOHA will be Master.

From a DNS point of view, the service must point to both VIPs.

In the example below, we configure two load balancers: LB1 and LB2 which would be respectively Master in VRRP instance inst1 and inst2 (and slave in the other instance).
